It's surprising but it also makes sense that there would be a completely separate wireless network for Internet of Things devices. "Existing wireless carrier signals make a lot of bandwidth available, but also require a lot of energy to maintain a connection to. IoT devices don’t need a lot of bandwidth. They just need enough to send data and receive commands." So using the low-energy network (eleven-x, in Canada, on a Low Power Wide Area Network (LPWAN)) these devices can greatly extend their battery life by "as much as 20 years," according to the article. The drawback is that the rollout is for high-density urban areas only.
